Chuck-will's-widow

The Chuck-will's-widow (Antrostomus carolinensis) is the largest nightjar in North America, named for its distinctive far-carrying call — a resonant four-syllable whistle repeated persistently on warm nights. It breeds across the southeastern United States, from the Atlantic coastal plain through the Gulf states and up the Mississippi Valley to southern Indiana and Kansas. The species migrates southward in autumn to winter quarters in the Caribbean, Central America, and northern South America. Like all nightjars, it is a crepuscular and nocturnal insectivore, capturing large moths, beetles, and other flying insects in flight using its enormous, bristle-fringed gape. By day, the Chuck-will's-widow roosts on the ground or along horizontal branches, relying on cryptic mottled plumage for concealment. It nests directly on the leaf litter of open woodland and scrub, typically in pine-oak forests, dry forests, and woodland edges. The IUCN classifies this species as Least Concern, though Breeding Bird Survey data suggest moderate long-term population declines linked to forest fragmentation and light pollution that disrupts insect prey availability. Conservation of large-scale woodland tracts in the southeastern United States benefits this species and its associated nightjar community.

Leopard

표범은 아프리카, 중동, 남아시아에 걸쳐 열대우림부터 사막까지 다양한 서식지에 분포하는, 지리적 분포 범위가 가장 넓은 고양이과 동물입니다. 단독 생활을 하며 주로 야행성이고, 먹이를 나무 위에 캐쉬해 두는 뛰어난 등반 능력을 가집니다. 흑변 개체인 흑표범은 밀림 개체군에서 흔히 나타납니다. 전 세계적으로 취약 등급으로 분류됩니다.
